The biological mechanisms associated between being overweight and sexual maturation remain unclear, but it has been established that overweight children have earlier sexual development. Objective: To determine the relationship between abdominal circumference and sexual maturation in female schoolchildren from educational institutions in the city of Merida, 2017. Methodology: Comparative, field and cross-sectional study was carried out, with a sample of 217 girls and adolescents from educational institutions, aged between 9 and 17 years. All girls with chronic diseases and endocrine disorders were excluded. Results: It was found that 132 girls (60.83%) presented a normal nutritional state, 36 (16.59%) and 49 (22.58%) of the remaining ones were below the norm and above the norm respectively. It was found that the average age of onset of menarche is inversely proportional to the nutritional status, this difference was not statistically significant. When comparing the abdominal circumference of normal girls and above the norm with the stage of development of the mammary gland (GM) and the stage of pubic hair (VP), a greater abdominal circumference was found for each stage of sexual maturation, being this difference statistically significant for all stages. Conclusions: The abdominal circumference is closely related to all the stages of sexual maturation, both for the mammary gland and for pubic hair, the greater the abdominal circumference the faster the Tanner stages are reached.

Abstract Aim Obesity is one of the leading public health problems in Mexico. Therefore, we investigated whether physical activity reduced the risks of mortality associated with obesity in participants in the Mexico City Prospective Study. Methods A total of 153,060 adults aged 52 (13) years were followed for 18 (4) years [mean (SD)]. Trained nurses asked about leisure-time physical activity and measured height, weight, and waist circumference. Cox models were adjusted for confounders and cardiovascular disease (CVD) and cancer mortality were treated as competing risks. Results There were 25,317 deaths from all causes, 8,488 from CVD, and 3,368 from cancer during follow-up. Compared with the group that reported little or no activity and had a normal body mass index, the hazard ratio (95 % confidence interval) for all-cause mortality was 1.40 (1.33, 1.47) in the group that reported little or no activity and had Obesity Class II. Physical activity reduced the risk of all-cause mortality associated with obesity. For example, the hazard ratio was 1.18 (1.06, 1.32) in the group that reported medium or high activity and had Obesity Class II. Physical activity also reduced the risk of CVD mortality associated with Obesity Class II and the risk of cancer mortality associated with Obesity Class I and Obesity Class II. Furthermore, physical activity reduced the risks of all-cause, CVD, and cancer mortality associated with high waist circumference. Conclusions This novel study suggests that leisure-time physical activity reduces the risks of mortality associated with general and abdominal obesity in adults in Mexico.
